Most soup today comes with tops with easy pull-off containers. Some other canned products do, too, like Spam and canned veggies. Most have a long shelf life. Most all canned food is already cooked. You can eat soup right out of the can. (Probably want to shake to mix first.) And, you can put the cans in a bag or plastic container with a big piece of paper with a list of expiration dates so you can easily check them from time to time. Use them at home and replace them when they get to their date. A nice big can of beef-veggie soup would taste a lot better than a granola bar. Pack couple of spoons in there, too.
